Izvi zvinorevei?

Iyi Generic Powertrain Diagnostic Dambudziko Kodhi (DTC) inowanzo shandiswa kune mazhinji OBD-II mota. Izvi zvinogona kusanganisira, asi hazvirevi kune, Mercedes-Benz, Jeep, Mazda, Ford, nezvimwe.

Kana iwe uine P009A kodhi nguva pfupi mushure meinjini sevhisi, zvinoreva kuti iyo powertrain control module (PCM) yaona kusaenzana muzviratidzo zvakabatana pakati peiyo sensor neiyo ambient tembiricha yemhepo. Izvo zvinodikanwa kuti uenzanise tembiricha yeIAT uye nemhepo ambient kuona kuti hapana zvipingaidzo zviri kutadzisa kuyerera kwemweya wakakosha kuenda kuinjini yekudyiwa.

Maseru eIAT anowanzo kuve neiyo thermistor inobudikira kubva kuimba yepurasitiki pane tambo mbiri-tambo. Iyo sensor inoiswa mukati mekupinda mumhepo kana mweya firita dzimba. Iyo yechipiri IAT sensor dhizaini inosanganisa iyo inzwa mukati memahara mweya kuyerera (MAF) sensor dzimba. Dzimwe nguva iyo IAT resistor inowanikwa yakafanana neiyo MAF inosimudza waya, uye mune dzimwe nguva inowanikwa muzororo kure nemhepo yekuyerera. Tarisa uone nzvimbo yeIAT sensor yemota iri mubvunzo usati waita fungidziro.

Iyo thermistor inowanzo gadzirirwa kuitira kuti mweya wekudya uyere kuburikidza nayo. Iyo muviri weiyo sensor inowanzo gadzirirwa kuiswa munzvimbo yekubatanidza kuburikidza nekobvu yerabha grommet. Sezvo tembiricha yemhepo yekudyira inokwira, mwero wekudzivirira muIAT unodzikira; zvichikonzera magetsi edunhu kuti asvike pakureva zvakanyanya. Kana mweya uchitonhora, kuramba kweiyo IAT sensor kunowedzera. Izvi zvinokonzeresa iyo voltage pane iyo IAT sensor wedunhu kudonha. Iyo PCM inoona shanduko idzi muIAT sensor signal voltage senge shanduko mukutora mweya tembiricha.

Iyo ambient mweya tembiricha sensor inoshanda nenzira yakafanana nenzira imwecheteyo seIAT sensor. Iyo ambient tembiricha sensor inowanzo kuve iri padyo nenzvimbo yegrill.

Iyo P009A kodhi inochengetwa uye isina kushanda chiratidzo mwenje (MIL) inogona kuvhenekera kana iyo PCM ikaona magetsi emagetsi kubva kuIAT sensor uye ambient tembiricha sensor iyo inopesana neinopfuura inopfuura yakanyanya kubvumidzwa kukosha kwenguva yakatarwa yenguva. Dzimwe mota dzinogona kuda kutadza kwakawanda kwekujekesa iyo MIL.

Chii chakakomba cheiyi DTC?

Iyo IAT sensor yekuisa yakakosha kune mafuta kuendesa uye yakachengetwa P009A kodhi inofanirwa kuverengerwa seyakakomba.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP009A injini kodhi inogona kusanganisira:

• Iyi kodhi inogona kuratidza kuti haina zviratidzo
• Injini yekudzora matambudziko
• Yakadzikira mafuta kunyatsoshanda

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi injini kodhi zvinogona kusanganisira:

• Sensiti yeIAT yakasara isina kubviswa mushure mekushandira
• Inokanganisa ambient tembiricha sensor
• Inokanganisa IAT sensor
• Vhura kana ipfupi dunhu mumatunhu kana zvinongedzo
• Yakakanganisa PCM kana PCM yekukanganisa kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P009A?

Ndisati ndaongorora iyo P009A, ini ndoda infrared thermometer ine laser pointer, yekuongorora scanner, digital volt / ohmmeter (DVOM), uye inovimbika mota ruzivo sosi.

Iyo yakachengetwa IAT sensor kodhi yakandikurudzira kuti nditarise iyo yemhepo firita chinhu. Inofanira kunge isina kuchena uye yakanyatsoiswa mukesi. Kuongororwa kunoonekwa kweiyo IAT sensor uye ambient tembiricha sensor wiring uye zvinongedzo zvinofanirwa kuitwa kana iyo yemhepo firita chinhu ichiita kunge iri kushanda nemazvo.

Ipapo ini ndakabatanidza iyo scanner kuchiteshi chekuongorora mota ndokutora ese makodhi akachengetwa uye kufomesa dhata data. Ini ndinowanzo farira kunyora iyi ruzivo pasi. Izvi zvinogona kubatsira sezvo nzira yekuongorora ichikura. Iye zvino ndaizobvisa makodhi uye kuyedza kutyaira mota kuti ndione kana iyo P009A yadzoswazve. Kwangu sosi yeruzivo rwemotokari inofanirwa kusanganisira madhirowa ewiring, chinongedzo mapini, zviyero zvekuyedza, uye mhando dzekubatanidza dzemotokari iri kutaurwa. Ruzivo urwu runenge rwakakosha pakuyedza wega maseketi nema sensors. Rangarira kudzima PCM (uye vese vanobatana vanodzora) kudzivirira kukuvara kune mutungamiriri kana uchiyedza yega masystem masisitimu ekuramba uye kuenderera neiyo DVOM.

Kuedza IAT uye Ambient Temperature Sensors

1. Shandisa DVOM uye sosi yako yakavimbika yemotokari ruzivo.
2. Isa DVOM pane iyo Ohm yekumisikidza
3. Dzingai sensor pasi pekuedzwa.
4. Tevera Chikamu Chekuyedza Chikamu

Maseru asingasviki bvunzo zvinodiwa anofanirwa kutorwa seasina kukwana.

Tarisa uone voltage uye pasi

1. Tarisa uone rinotenderera wedunhu remumwe munhu IAT uye ambient tembiricha sensor zvinongedzo vachishandisa iyo yakanaka bvunzo tungamira kubva kuDVOM.
2. Tarisa pasi chinongedzo chisina kunaka bvunzo inotungamira.
3. Nekiyi yakavhurwa uye injini yabviswa (KOEO), tarisa revhizheni voltage (kazhinji 5V) uye pasi pane yakasangana sensor zvimiro.

Tarisa IAT uye Ambient Temperature Sensor Signal Circuits

1. Unganidza iyo sensor
2. Edza dunhu rechiratidzo re sensor yega yega neyakajeka bvunzo inotungamira kubva kuDVOM.
3. Iyo isina kunaka bvunzo inotungamira inofanirwa kuve yakabatana kune inozivikanwa inozivikanwa mota yepasi kana uchiyedza iyo chiratidzo yedunhu.
4. Shandisa infrared thermometer kuti utarise chaiyo IAT uye ambient tembiricha.
5. Tarisa iyo scanner data kuyerera uye uone izvo IAT uye ambient tembiricha kukosha zvakapinda muPCM kana ...
6. Shandisa iyo tembiricha uye voltage chati (inowanikwa mune mota ruzivo sosi) kuona kana sensor yega yega iri kushanda nemazvo.
7. Izvi zvinoitwa nekuenzanisa iwo chaiwo magetsi eiyo sensor chiratidzo wedunhu (inoratidzwa paDVOM) nemhepo inodiwa.
8. Kana paine chero ma sensors asiri kuratidza iwo chaiwo voltage nhanho (zvichibva pane chaiko IAT uye ambient tembiricha), fungidzira kuti ichi chinhu chakaipa.

Kana maseketi emasaini eIAT uye ambient tembiricha sensor inoratidza inoenderana voltage kukosha

1. Tarisa chiratidzo wedunhu (kune iyo sensor iri mubvunzo) paPCM connector uchishandisa iyo DVOM.
2. Kana paine inoenderana sensor chiratidzo pane iyo sensor yekubatanidza iyo isiri paPCM yekubatanidza, fungidzira kune yakavhurika dunhu pakati pezviviri.

Bvisa zvimwe zvese zvingasarudzika uye fungidzira PCM kutadza (kana PCM kuronga chikanganiso) chete kana ese maIAT uye ambient tembiricha maseru nematunhu ari mukati mezvakatemwa.

Technical Service Bulletins (TSBs), iyo inochengeta mota data, zviratidzo, uye makodhi, zvinonyanya kubatsira kukubatsira kuongorora.
